Tunnel

While Jung-soo struggles to survive, a series of ridiculous blunders delays the rescue operation and threatens his chances to make it out alive. Soon, he runs out of food, water, and phone batteries, making him totally incommunicado. Days pass without any progress and people start to lose hope or interest in rescuing him. Having already passed the longest survival record for a disaster, hard decisions are forced on his family while no one knows whether Jung-soo is dead or alive.
